Here is at a gene sequence from clear lake hitch that I found on Genbank. There are more. Im not sure why he thinks they are introgressed? I haven't read that anywhere?

There is pretty good evidence that this is a unique species. Differences in the gill arches that would make sense for a more lake-oriented feeding habit as they are used in filering algea and plankton, and a deeper body, also often associated with slow and still-water environments.
Lastly...someone find me a good definition of a subspecies :)
